However, the above-mentioned rubber rain boots have the following disadvantages in wearing: First, due to the relatively dense rubber material, the rubber rain boots are relatively stiff and heavy, and when worn for a long period of time, the user's feet are greatly caused. The load and bending resistance cause discomfort. 2. Although the above rubber rain boots can be waterproof, they cannot be drained from the inside to the outside. Therefore, under long-term wear, the sweat moisture discharged from the user's feet cannot be discharged and accumulated in the rain boots, thereby allowing the feet to be worn. The feeling of wearing is quite stuffy and uncomfortable.

Therefore, the object of the present invention is to provide a moisture-permeable waterproof shoe that is lightweight and has a full upper surface that can achieve a moisture-permeable waterproof effect.

Thus, the novel moisture permeable waterproof shoe comprises an upper, a waterproof unit, and a sole.

The upper is sewn from a plurality of upper panels, each upper panel comprising an inner lining, an outer base fabric attached to the inner lining, and a outer base fabric opposite to the inner lining The moisture permeable waterproof film on the surface of the cloth, the inner lining of the upper piece of the upper piece cooperates to define a wearing space for the foot to penetrate.

The waterproof unit covers the seam where the upper is disposed to prevent water from entering the installation space from the seam of the upper.

The sole is affixed to the outer bottom of the upper.

The utility model has the advantages that the moisture permeable waterproof film of the upper and the waterproof unit covering the seam provided on the upper cooperate with each other, so that the new moisture permeable waterproof shoes can achieve the function of moisture permeability and waterproofness of the whole upper. That is to say, the moisture permeable waterproof shoe has the advantages of moisture permeability and waterproofness compared with the existing cloth, textile or natural leather footwear, and has the advantages of moisture permeability compared with the existing synthetic leather footwear and rubber rain boots, and further, each The upper piece adopts the three-layer structure of the inner lining cloth, the outer base cloth and the moisture permeable waterproof film, and the weight thereof can be effectively reduced substantially compared with the existing natural leather or synthetic leather upper and the rubber upper, and The new moisture-permeable waterproof shoes can achieve soft and comfortable wearing under light weight. Finally, the upper is sewn from the upper cut pieces. Compared with the existing rain boots, the one-piece injection molding is not only free. To develop and make molds, and by cutting out different shapes of upper pieces, we can make waterproof shoes with different shoes, such as casual shoes, sports shoes, and long and short boots.
